Just in case 420 horsepower isn’t enough for you on your 2015 Cadillac Escalade, just give Hennessey Performance (HPE) a call and they can amp up the 6.2-liter Ecotec3 V8 to 557 ponies.

For $15,950, this big boost in horsepower comes with a belt-driven supercharger, air-to-water intercooler, recalibrated engine management software, and even a three-year/36,000-mile powertrain warranty. The engine’s torque sees an upgrade too, at 542 lb-ft compared to 460 lb-ft on the factory engine.

In addition to the engine upgrades, the HPE550 package will add upgraded fuel injectors, Hennessey badging, Hennessey embroidered floormats, and you’ll get the satisfaction of leaving the Mercedes-Benz GL63 AMG and Land Rover Range Rover Sport in your tracks. And, if you want to improve your performance even more, you can add the HPE 20-inch H10 forged monoblock wheels.

If you’re dreaming of this supercharged Cadillac, you have to get your hands on the 2015 Escalade first. Come visit us at Crest Cadillac today where we have the 2015 Escalade available now.
